Emerald Rose by Emma Hamm

A beast attacked me.
A beast called the Dread.
But the attacker spared my life.
He offered to train me to fight.
As a princess, I’d always been locked away in a tower.
I was never allowed to be a warrior.
My training begins underneath my own kingdom.
A place where the Dread live.
I remind him of his human life.
I’m the only one who can save his real identity.
But first we’ve got something bigger to handle.
A war between our people.
How are we going to stop it?
